Piggyback direct seed with underfloor fertilization and a working width of 6.5 m, prototype
Hello Com,
since I enjoy the whole standard machines from Amazone color were boring and I have no Aufsattelbare seeder with reasonable working width found, I have just selbstgebastelt one.
The Bednar is designed for direct seeding, so it must not be previously grubbed or plowed. Furthermore, it is equipped with underfloor fertilization of Webalizer.
This mod is built according to my ideas, it is not forced to download.
Who the mod does not fit just play with something else and leaves no pointless comments.
Meaningful criticism and suggestions are welcome.
